Brompton is a British manufacturer of folding bicycles which are company's core product, noted for its self-supporting compact size when stored. The modular design has remained fundamentally unchanged since the original patent was filed by Andrew Ritchie in 1975, with small details being refined by continual improvement. Bikes are still made in London to ensure that every one of their bikes is built to the highest standard. Their bikes are featured on Boltano Yacht Supply website, as well as the spare parts for them.
